GEAR-LOCK For, AUTOMOBILES.

- Be it known that I, CHARLES G.-TROsIEN, a citizen ofthe United States, residing at Pontiaq county ofOakland, State of Michi an,-liave invented a certain new and useful mprovement in Gear-Locks for Automo- I 1 biles, and declare the followingto be a full,

clear and exact description of the same, asiwill enableothers skilled in the art to reference; being had to the accompanying which it;pertains tomakeand use the same,

drawings, which form apart of this specificati'on.-

My invention relates to gear locks f or' automobiles and a special ob ect of my improvements is to provide a lock which is simple in construction, complete in itself, and may. be readily applied to automobiles in general use.

I secure this object in the device ill" trated in the accompanying drawings All Figure 1 is a part sectional'elevation of a gear casing with a lock embodying my invention applied thereto.

Fig. 2 is an inverted plan view of the Same.

. .Fig. 3 is an elevation of the lock separate from the gear casing.

v Fig. 4 is a sectional view of the lock and a pFpi'tionof the gear casingadjacent thereto 1 ig. 5 is a section on the line 55 Fig. 4.

Fig. 6 is a view similar to Fig. 5 showing the parts in lockin position.

Fig. 7 is an e ovation of the rotating spindle detached from its casing.

Fig. 8 is a view similar to Fig. 4 showing a modified construction.

Fig. 9 is a section on the line 99 Fig. 8.

a is the casing for the change speed gear. b is the shifting lever and c c are the parallel the ears.

Fig. 3 shows the lock as manufactured ready to be adjusted to position on the gear casing. 11 is a cylindrical casing which I preferably make of greater diameter above and reduced, as shown at d", below. (Z indicates a diametral passage extending horizoritally through the casing d at its lower enc.

e is a rotatable spindle fitting in the casing cl coaxially therewith. At the upper end of the rod 6 there is located a locking device which may be a pin lock or of similar con- Specification of Letters Patent.

struction. There isa key .v (Figs. land 8) which is inserted in a slot in the upper end -of-the part cf of the rod, or spindle, 6 and when so inserted adjusts the locking bars g (Flg, 4).. to a position to'permit the turning of said spindle. When the. key m is withdrawn the bars 9 engage the casing if and prevent the turning of the spindle c.-, .1

The lower end of the spindle e is'cut away ,on bpth-sides to form a cam e and balls f "lit?v are inserted in the passage oraperture d one at each-side of-said cam. The walls of the casing at the ends of the apertured are pressed inward, to prevent the balls f from fallingout of the passage d,

When the spindle e is at the position indicated in Fig. 5 the "cam e permits the balls f f to enter fully Within the passage d When the spindle is turned at rightangles and to the position shown in Fig. 6, the balls 7 5 f f are forced outward so that they pro-- trude from said passage.

The method of adjusting the lock to the gear casing is as follows: A circular hole is bored in the cover or upper surface of the 8 gear casing between the rods 0 0 and said rods are placed in their neutral position and apertures c are formed in said rods opposite each other of a shape and size a da%)ted1 ,-8= mm" 5 to receive the balls f f when protruded v the aperture d in the casing d. The casing 'd is then inserted in the hole bored'in thei top of the gear casing so that;.itoccupies;

the space between the rods jcYfWith the apeiaj, time d and the balls therein in line a with n the aperture 0 in the rod. The casing is of such a size as to just occupy the space between the rods. The casing dbeing thus-in-- serted through the apertiire in the gear cas thenwelded to said easing... Now, if.

tion in line With the aperture (Z the ballsgf will be entirely within said aperture and when the spindle e is turned to the position shown in Figs. 8 and 9 the forks or cams 110 and partly into the Thus when at" the lon'eikenrl .will pass hut-Ween the halls and force the outer halls intq locking pi mriion.

It will be bbservil that this lock inky be iiizuhs romplcte in itself and readily adjustecl in position upon a form of changespee lgmirii in common use and readily secured s rimi; that the spindle is supported lmrer will by ihe (Ewing's-3 as to 59- lmhl the billS when the lock en 4 1 bars; that (he look is of simple .Ulltwailllflflflli mmipying hut little ielidilyniaiiipulzitrl,
